In a large population, 92% of the households have cable tv. A simple random sample of 225 households is to be contacted and the sample proportion computed. What is the mean and standard deviation of the sampling distribution of the sample proportions

the mean and the standard deviation is 0.92 and 0.01808 respectively

Step-by-step explanation:

The computation of the mean and the standard deviation is shown below:

The mean is 0.92

And, the standard deviation is

= √0.92 × (1 - 0.92) ÷ √225

= √0.92 × 0.08 ÷ √225

= √0.0736 ÷ √225

= √3.27

= 0.01808

Hence, the mean and the standard deviation is 0.92 and 0.01808 respectively

second option, a whole number constant could have been subtracted from the exponential expression.

Explanation:

1) The parent exponential function can be writen in the form f(x) = Aˣ

2) That exponential function has asymptote y = 0, which you determine by doing the limit of f(x) when x goes to negative infinity:

3) Therefore, an asymptote y = - 3, is represented by a constant traslation of the parent function 3 units down.

And that is f(x) - 3, which means that the whole number 3 had been subtracted from the exponential expression.
